Your furnace keeps your you warm during the harsh winter months, so it’s frustrating when something is wrong. One common issue is a furnace that endlessly kicks on and turns off all the time. This problem is called short cycling. It stresses your furnace and may lead to pricey repairs or even premature replacement.
Short cycling can be the result of for varying reasons. Before you book furnace repair, research the likely causes and how to take care of the problem.
1. Clogged Air Filter
The HVAC filter attracts airborne dust, hair and other substances that could wreak havoc on furnace. If you don’t change the filter often enough, it can get clogged and decrease the airflow. When this takes place, a safety mechanism switches off the furnace to stop overheating. Pull Out the filter, and if it’s dirty, install a new one. Going forward, get a new filter every 30 to 90 days to prevent your furnace from short cycling.
2. Obstructed Air Vents
A dirty filter isn’t the only trouble that can reduce airflow and overheat your furnace. Walk around your house and look for closed or obstructed air vents. For proper system balance and performance, keep all registers open, even in unused rooms.
3. Dirty Blower Wheel
The furnace blower uses blades that distribute air through the ductwork. If they are caked with dirt, the air won’t move properly, creating overheating and short cycling. Regularly putting in a new the filter is the easiest approach to avoid a dirty blower wheel. If the blades are already dirty, schedule furnace maintenance to have them cleaned.
4. Faulty Thermostat
Check your thermostat next. This is the cortex of your HVAC system and gives the furnace instructions on what to do. Ensure the thermostat is in heating mode and auto fan with the desired temperature displayed on the screen. Try changing the batteries. Also, check whether the thermostat is in full sunlight or near a heat source that could affect the temperature reading. If you use a smart thermostat, check the manufacturer’s site for troubleshooting instructions.
5. Soot-Covered Flame Sensor
The flame sensor turns off the gas valve when no burner flame going. The sensor can’t sense the flame if it’s sooty, so the gas turns off prematurely and the furnace turns off. Leave the adjustment of repairing a sooty flame sensor to an Expert like Calverley Service Experts.
6. Oversized Furnace
When it includes home comfort equipment, oversized isn’t always best. A bigger system heats up your home too fast, leading to uncomfortable temperature swings and short cycling. The only way to resolve this problem is to do new furnace installation.
